Cloud streets streak across the Bering Sea and the Gulf of Alaska in this true-color Aqua MODIS image from March 14, 2003. Over the ocean, clouds will often align in the direction of a low-level wind, which produces parallel rows or streets of clouds. Alaska's Aleutian Islands interrupt the airflow, creating a kind of wake effect in the clouds at image lower left.

These streets can and do happen all over the world: the South China Sea, off of the Cape Verde Islands, south of the Kamchatka Peninsula, etc. In essence, these cloud types can form over any body of water with some sort of obstacle big enough to disturb air flowing past (generally an island).
